Jeopardy! Shows Humans Don’t Maximize Profits


Investor-UpdateOne of the common behavioral biases is anchoring. Anchoring is basing expectations and viewpoints on previous, often recent, information. An example would be the yield on the 10-year Treasury note. The benchmark bond yielded 1.59% today. If it were to rise over the short term to, say, 2.0%, your opinion would likely be that rates have jumped even though a 2.0% yield would still be lower than it was a year ago. The human mind focuses more on the available information (e.g., today’s yield) than on information requiring more cognitive effort to access (e.g., the yield from 12 months ago).

Anchoring has been long believed to influence many of our financial decisions. Though it can be replicated in experiments, its effect is harder to prove in real-world environments. Two researchers found a creative way to prove anchoring occurs when decisions have a direct monetary effect: They analyzed decisions made by contestants in the game show Jeopardy!

Jeopardy! primes contestants with actual dollar values. Every clue is preceded by a dollar amount. A contestant could choose to take “Sports” for $800, for instance. A correct answer immediately increases a contestant’s winnings by the specified dollar amount, while an incorrect answer decreases winnings. Hidden on the board are three special clues, called “Daily Doubles.” Daily Doubles allow a contestant to chose to wager any amount up to his or her entire account balance or the largest dollar value on the board, whichever is bigger. A contestant does not know if a clue is a Daily Double until a category and wager amount is chosen (e.g., World History for $600). This fact makes Daily Doubles interesting from the standpoint of behavioral economics.
